DISH-CLEANER.

Specification of Letters Patent. I

Application filed May 16, 1910. Serial No. 561,783.

To all whom it may concern:

Be it known that we, ELLET SANBORN and A NGUS K. MAoDoNALo, citizens of the United States, residing at Portland, in the "county of Cumberland and State of Maine, have invented new and useful Improvements in Dish-Cleaners, of which the following is a specification.

This invention relates to improvements in dish cleaners. Its object is to provide a dish cleaner which can be connected with a hot water plant so that a supply of hot Water under pressure can be directed upon the dishes.

It also relates to improvementsfor charging the water from the hot water tank with a cleansing compound as soap, soap powder, etc, before it strikes the dishes.

It also relates to certain details of construction hereinafter described and specifically claimed.

In the drawings herewith accompanying and forminga part of this application, Figure 1 is an elevation partly in section of our improved dish removed; Fig. 2 1s a vertical central sectional view taken on line XX, Fig. 1, looking toward the right; Fig. 3 is a detail of one of the operating arms: and Fig. 4 1s a fragment ofthe top of the basket. I

.Same reference characters indicate like parts in the several figures.

In the drawing ing and forming a part of this application A is a tank of any suitable con-' struction provided. with a cover B which may be hinged thereto, if desired, by a hinge C, the pivot point of the hinge preferably being positioned far enough beyond the edge of the tank to permit the cover to be entlrely removed. The hinge, however, may be omitted, if desired.

Near the bottom of the tank is set a spindle bearing D and mounted the dish container E which is provided with a hub F and rotate thereon. The CllSh container should be freely open at the sides and bottom to admit water into all parts thereof. The dish container is rotated by means of radial armsG secured to a hub H fixed on a shaft I projecting upwardly through the top of the cover and through a bearingJ secured thereto to hold it firmly against lateral movement. The shaft is provided with cleaner, the container being herewith accompanyupon this I spindle is to engage said spindle I a crank or' wheel K by means of which it can be rotated. The outer ends of the radial arms G are adapt d to take into the depressions L in the upper edge of the container so that the rotation of. the shaft and its arms imparts corresponding rotary motion to the container upon its bearing. The outer ends of the radial arms G are provided with curved or inclined positioning devices M which serve to center the top of the dish container and cause it to rotate steadily on its bearing.

Secured to the inside of the tank is a perforated pipe N entering the tank preferably near the top from one side through a sleeve 0 and thence extending downwardly close to the walltransversely across the tank near the center and then upwardly near the opposite wall terminating preferably at a point near the .to of the tank. The vertical parts of this pipeare provided with openings,.some P being in a direct radial line with the center of the tank and others Q slightly to one side thereof, the openings Q in one of the vertical parts of the pipe beingin the side opposite to those in the other whereby the force of the water directed upon the dishes in the container from the side openings Q strike the dishes-in a tangential direction and tend to cause the container to rotate on its bearings. The horizontal part of the ipe is provided with similar openings R t projected upwardly at various angles through the bottom of the container upon the dishes contained therein. The pipe N extends above the sleeve 0 and is provided with a couplin S by which it is attached to a supply pipe leading to the water supply, not shown. We also provide a perforated pipe T entering the tank at some convenient pointthrough which a blast of air can be directed upon the dishes in the container from a blower, not shown, connected thereto at'U. Connected with the pipe N is a receptacle V adapted to contain a cleaning compound. Leading from a point near the bottom of the receptacle to the water supply pipe N is an inlet pipe W and leading from said receptacle to said low the connection of the pipe W therewith -is an outlet pipe X provided with a valve Y for controlling the supply of water therethrough. The bottom of the tank is provided with an opening Z for the escape of waste water therethrough.

Patented Oct. 1, 1912.

rough which water is pipe N at a point be- The operation of our device is as follows :-The tank is preferably positioned in a wet sink so that the water may be allowed to pass freely out from the opening Z. The

dishes to be cleansed are placed in various positions in the container which is removably mounted in the tank, the cover closed and the container rotated in any convenient manner. The water supply is then turned on through the perforated pipe N and as the containerrotates a spray of'water is directed laterally and vertically against the dishes contained in'the container, the water being charged with a supply of cleaning compound from the receptacle V, a portion ofthe water passing from pipe N through the small pipe W to the bottom of the receptacle and thence upwardly and through the pipe X again into pipe N mingling with the main stream. The quantity of cleaning compound can be readily regulated by means of the regulating valve Y in the pipe. As soon as the dishes are thoroughly'washed valve Y is closed and the dishes can be rinsed with clear water' through the same pipe. The supply of water through the pipe N is then shut off and the dishes allowed to dry in the tank or they may be removed and set upon the stove or they may be dried by an air blast through pipe T where such a blast is readily obtainable.

The advantages of our improved dish cleaner are:that it washes the dishes thoroughly without handling them; it is cheaply constructed and easily operated. Another advantage is that the supply of water is automatically charged in its passage from the reservoir supply of cleaning compound, the proportion of which can be readily regulated. Another advantage is that the container is readily connected to and disconnected from to the dishes with a the operating mechanism by merely raising the cover to the tank. Another advantage is that the supply of cleaning compound can be entirely shut off when desired and clear water sprayed upon the dishes through one and the same pipe.

It will be noted that water is not used a second time and therefore the apparatus possesses a great advantage over those dish cleaners wherein the container is rotated in a constant body of water.

Having thus described our invention and its use, we claim 1. In a dish container, a tank provided with a spindle in the bottom thereof, a dish container provided with ahub adapted to engage and rotate upon said spindle and with depressions in its top edge space apart at frequent intervals, and a shaft provided with radial arms having their outer ends adapted to take into said depressions and impart rotation to said container.

2. In a dish cleaner, a tank provided with a spindle in the bottom thereof, a dish container centrally positioned and provided with a hub adapted to engage and rotate upon said spin'dle'and with depressions in its top edge spaced apart at frequent intervals, a shaft provided with radial arms having their outer ends adapted to take loosely into said depressions and impart rotation to said container and provided with longitudinally curved centering devices on their free ends adapted to engage the container at a plurality of points to center it relative to the spindle.
